Abstract: A position control for a crop pickup device which is mounted for vertical movement relative to an agricultural harvester. A measuring device is provided for determining the distance from the crop pickup device to the ground, wherein the position of the crop pickup device relative to the ground is adjustable by one control device as a function of the measured ground distance. The distance to the ground is determined by the measuring device at two points spaced from each other in the direction of travel. As a result, advantageously the inclination of the ground can be determined and used for optimized control of ground simulation of the crop pickup device. Additionally, the cutting angle can be adapted automatically to the slope of the ground, to avoid crop losses and impede damage to the grain header.

Abstract: In an agricultural machine having a machine housing, a main drive axle with pivotal drive wheels, and a feed rake, an apparatus for allowing pivotal adjustment of a frontal attachment relative to the feed rake includes at least one pivot element or frame pivotally connected between the feed rake and the frontal attachment, thereby creating at least two separate pivot planes between the frontal attachment and feed rake. The pivot element pivots about a pivot axis that is generally coaxial with a crop path through the feed rake.

Abstract: A conveying device for stem-bearing crops which is provided with two rotatable circular blades and two rotatable housings above for receiving tines, is to be designed in such a way that the tines are fixed to the rotatable housing in such a way that the risk of breaking is substantially reduced, so that the service life of the tines is substantially increased. The tines are permanently inserted in bearing plates. Each bearing plate is mounted freely rotatably on a fixed bearing pin, the longitudinal center axis of the bearing pin being parallel to and spaced apart from the axis of rotation of the cylindrical housing. On the bearing plate on the outside on two bolts are mounted roller bearings which roll over the control face of a control cam which is also mounted on the bearing pin. The control cam is not rotatable relative to the bearing pin, but slidable in the axial direction, and is pressed by a plate spring assembly toward the roller bearings.
